Cohesion between sister chromatids occurs during DNA replication, is regulated by cohesin, and depends on acetylation of cell division cycle associated 5 (CDCA5) and cohesin. WAPL can promote dissociation of cohesin from DNA, and CDCA5 can antagonize the effect of WAPL and stabilize sister chromatids cohesion by stabilizing the binding of cohesin to DNA. CDCA5 mRNA has a high transcription level in a variety of tumor cell lines, suggesting that CDCA5 may be related to the higher malignant proliferation activity of tumor cells, and has been confirmed in various tumors such as liver cancer and lung cancer, and CDCA5 may be a potential targeted molecule for the treatment of malignant tumors.

OBJECTIVE:To investigate the effects and safety of Xingnaojing injection combined with butylphthalide on neuro-logical function,cognitive function,coagulation function and living activity. METHODS:A total of 106 patients with middle cere-bral artery infarction in Wuhan University People's Hospital during Jun. 2014-Dec. 2015 were divided into control group and obser-vation group according to random number table,with 53 cases in each group. Besides routine symptomatic treatment,control group was given Butylphthalide soft capsules 0.2 g,po,tid. Observation group was additionally given Xingnaojing injection 20 mL added into 0.9% Sodium chloride injection 250 mL,ivgtt,qd. Both groups were treated for 14 d. The neurological function score (NI-HSS,NFDS),cognitive function score (MoCA,MMSE),coagulation function indexes (PT,APTT,FIB),BI score were ob-served in 2 groups before and after treatment. The occurrence of secondary remote damage and ADR were recorded. RESULTS:Eight patients withdrew from the study,including 3 patients of control group and 5 of observation group. Before treatment,there was no statistical significance in neurological function scores(NIHSS,NFDS),cognitive function scores(MoCA,MMSE),coag-ulation function indexes or BI scores between 2 groups (P>0.05). After treatment,NIHSS,NFDS scores and FIB of 2 groups were decreased significantly compared to before treatment,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). MoCA,MMSE,BI scores in 2 groups were increased significantly,and PT and APTT in 2 groups were prolonged significantly,and the observation group was significantly higher or longer than the control group, with statistical significance (P<0.05). The incidence of secondary remote damage in observation group (11.3%) was significantly lower than control group (41.5%),with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:For middle cerebral artery infarction,the application of Xingnaojing injection combined with butylphthalide can reduce the risk of remote damage,promote the recovery of neurological function and cognitive func-tion,and improve coagulation function and living activity with good safety.

Objective:To observe the protective effects of Clostridium butyricum and butyrate on pancreas, liver and intestinal mucosa in rats with acute necrotizing pancreatitis (ANP), and to explore the possible mechanism.Methods:Forty Sprage-dawley rats were randomly divided into control group, ANP group，Clostridium butyricum treated group(CB group) and butyrate treated group(SB group), with 10 rats in each group by random number method. The ANP rat models were prepared by retrograde injection of sodium taurocholate into the biliopancreatic duct. Rats in CB and SB group were given intragastic administration of Clostridium butyricum 1×10 9 CFU or sodium butyrate (100 mg/kg) in 10 days once a day before modeling. Serum amylase (SAMY), lypase, ALT, AST, TBil, tumor necrosis factor alpha(TNF-α), IL-6 and HMGB1were measured after 24 h. Protein from intestinal mucosa was extracted and Western Blotting was used to measure expression of tight-junction proteins ZO-1, claudin-1 and occludin. Pancreas and liver tissues were stained with hematoxylin-eosin and scored by pathology. Results:The levels of amylase [(9365.1±716.5), (5947.3±512.0), (6517.7±269.6)U/L], lipase[(8343.7±1041.4), (6600.4±899.7), (6754.4±1046.4)U/L], AST[(560.5±72.7), (432.0±76.2), (429.8±40.5)U/L], ALT[(499.9±65.2), (385.7±46.0), (395.8±45.8)U/L], TBil[(134.2±56.2), (74.3±65.2), (81.3±35.3)U/L], TNF-α[(162.0±14.4), (100.4±6.3), (119.2±12.5)ng/L], IL-6[(161.4±26.0), (104.8±15.2), (105.5±12.7)ng/L], HMGB1[(100.1±6.7), (58.0±7.7), (63.4±7.2)ng/L] in ANP group, CB group and SB group were detected; and the pathological scores of pancreas[(11.2±1.08)，(9.45±1.06), (9.04±0.89)] and liver[(2.89±0.73), (2.09±0.49), (2.12±0.52)] in ANP group，CB group and SB group were higher than those in control group[(100.6±5.20)U/L, (966.5±301.9)U/L，(30.2±6.3)U/L, (27.6±5.9)U/L, (2.4±0.6)U/L, (29.5±4.8)ng/L，(36.9±7.6)ng/L，(35.5±5.7)ng/L，(1.18±0.05)，(0.56±0.09)]. However, those indexes in CB group and SB group were lower than those in ANP group, and the difference was statistically significant (all P<0.05). The expression of ZO-1 in control group, ANP group, CB group and SB group was 1.83, 0.79, 1.25 and 1.16. The expression of claudin-1 in control group, ANP group, CB group and SB group was 0.58, 0.13, 0.43 and 0.37. The expression of occludin in control group, ANP group, CB group and SB group was 1.06, 0.38, 0.82 and 0.79. The expression of TJ proteins in ANP group was significantly lower than that in other groups and the difference was statistically significant (all P<0.05). Conclusions:Clostridium butyricum and metabolites butyrate can alleviate the inflammatory response in ANP rats with liver injury, maintain the function of intestinal mucosal barrier and prevent the liver injury.

Objective To investigate the changes in blood pressure and serum norepinephrine after stretching the superior cervical sympathetic ganglia.Methods The superior cervical sympathetic ganglia of 10 rabbits were stretched to simulate the physical stimulation of cervicogenic hypertension.The blood pressure and content of norepinephrine in serum were observed and the observations were correlated.Results The rabbits' blood pressure had risen significantly after the stretching.The content of norepinephrine in serum had also increased significantly.The changes in blood pressure and norepinephrine content showed significant correlation.Conclusion The changes in blood pressure and serum norepinephrine after stretching of the superior cervical sympathetic ganglia show significant correlation,at least in rabbits.

Objective To explore the effect of pulling cervical sympathetic ganglia on blood pressure of experimental rabbit. Methods Anesthetized experimental rabbit were dominated the change of blood pressure with intubation via femoral artery. The electrocardiogram was recorded with standard lead II of electrocardiography, the cervical sympathetic ganglia was separated and the ganglion was ligated, with 20 g quality to the ventral top force, then the blood pressure was recorded and analyzed. Results Before pulling, the blood pressure maintained at 110/80 mmHg, and during the process of separating the neck nerve, the blood pressure increased temporarily. During pulling cervical sympathetic ganglia, it decreased about 20 s and then increased gradually and maintained at 125/90 mmHg until the end of pulling. Conclusion Pulling cervical sympathetic ganglia could significantly increase the blood pressure of experimental rabbit.

Objective To investigate the use of parenteral nutrition in hospitalized patients and to examine the process of care of patients receiving parenteral nutrition (PN) in hospital, in light of European Nutrition Day study, and to preliminarily explore the possible main risk factors for complications.Methods We recruited 314 adult hospitalized patients (≥18 years) requiring PN on a predetermined day (November 25, 2013) in 6 hospitals in Beijing and investigated their disease status, nutrition risk, the use of PN and venous infusion related complications using the European Nutrition Day survey questionnaire.Results Of the 314 patients, 311 completed the survey.In the 311 patients, the proportion of patients who received PN of all-in-one mixed preparation was 76.2％ (237/311), the proportion of patients receiving multibottle system was 23.8％ (74/311);PN was administered via central vein in 56.8％ (171/301) of the patients and via peripheral veins in 43.2％ (130/301) of the patients.The mean duration of infusion was (12.5 ±5.1) hours.The ratio of glucose to fat was 0.84 and the ratio of non-protein to calories 531.1.The total energy provision was less than the recommended intake.38.6％ (120/311) of the patients reported that PN infusion would affect activity, and 33.4％ (104/311) thought PN affected their sleep, and the incidence of infusion-related pain was 19.9％ (62/311).Multivariate analysis result showed that the most important factors of infusion-related pain were intravenous route of PN (x2 =25.911,P =0.000) and total venous infusion volume (x2 =6.053, P =0.014).Conclusions The total energy provision of PN is generally inadequate in hospitalized patients in Beijing.The key factor for reducing transfusion-related pain and enhancing PN tolerance is to establish appropriate infusion route.

Objective To explore the relationship between interleukin 1 receptor accessory protein-like 2 (IL1RAPL2) gene and cognitive abilities of children in Qin-Ba mountainous region. Methods Four tagged SNPs (rs5962434,rs5916817, rs3764765 and rs5962298 ) in IL1RAPL2 were selected, and then genotyped by PCR-SSCP method in a 320 children sample aged from six to fourteen years old. Results The results showed the rs5962434, rs5916817 ,rs3764765 and rs5962298 had no deviations from Hardy-Weinberg equilibrium (P＞0.05),and there were no significant statistical differences in the average psychometric scores of general cognitive ability(P=0.81,0.53,0.79,0.90) ,verbal comprehension (P=0.58,0.47,0.69,0.87 ) ,memory and concentration (P=0.69,0.35,0.76,0.90) among the compared genotype groups at each of the markers. Furthermore,the results also indicated that the four SNPs were not associated with perceptual organization in males and females respectively (P = 0.70,0.85,0.76,0.90,0.65,0.22,0.98,0.90 ). Conclusion The present work suggests that the human general cognitive ability, the three cognitive factors of C-WISC scale are not influenced manifestly by the genetic variations in IL1RAPL2.

Objective To investigate the association between the genetic polymorphisms in GSTA1 and the clinical outcome of breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy. Methods A total of 137 breast cancer patients receiving cyclophosphamide-based adjuvant chemotherapy were recruited ( 124 cases with infiltrative ductal carcinoma, 5 cases with infiltrative lobular carcinoma and 8 cases with other histological types). PCR-LDR method was used to detect the genotypes of GSTA1. Survival curves were generated by the Kaplan-Meier method, and verified by the log-rank test. Cox proportional hazards regression analysis was used to estimate the prognostic factors in multivariate analysis. Results Of the 137 breast cancer patients, the genotypic frequencies of the GSTA1 * A/* A,* A/* B and * B/* B were 67.2% ( 92/137 ), 31.4% ( 43/137 ) and 1.5% ( 2/137 ), respectively. No significant differences were found between the genotypic frequencies and groups categorization according to age, stage, lymph node metastasis, ER or PR status (x2 = 0. 722,1. 967, 3. 303, 0. 226 and 0. 709, all P ＞0. 05 ) ;through Fisher exact test, also no significant differences were found between the genotypic frequencies and group categorization according to tumor size, histological types and grading ( all P ＞ 0. 05 ) . The recurrence rates in patients with GSTA1 * A/* A and * A/* B or * B/* B genotypes were 47. 8% (44/92) and 31.1% ( 14/45 ), respectively, and the mortality rates were 22. 8% ( 21/92 ) and 17. 8% ( 8/45 ),respectively. Patients with GSTA1 * A/* B and * B/* B genotypes were significantly associated with reduced hazard of relapse (x2 =18.723, P＜0. 01)and mortality (x2 =7.352, P＜0.01), compared to cases with the common * A/* A genotypes, according to Kaplan-Meier survival analysis and log-rank test. Moreover,Cox multivariate analysis showed that GSTA1 polymorphisms appeared to be an independent risk factor for recurrence-free survival ( OR =0. 222, 95% CI:0. 108-0. 458, P ＜0. 01 ) and overall survival ( OR =0. 362,95% CI:0. 145-0. 902, P ＜ 0. 05 ). Conclusion These data indicate that GSTA1 polymorphism may be a potential prognostic factor for recurrence-free survival and overall survival in breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy.

Objective To evaluate the effect of enteral nutritional support for the liver cancer patients with precise hepatetomy under fast track process model. Methods 82 patients were prospectively randomized into enteral nutrition group (n = 41) and parenteral nutrition (n = 41). The hemoglobin (HB), total protein (TP), albumin (ALB) and total lymphocyte count (TLC) were measured on 3 days before operation and 7 days after operation respectively. The two groups were compared in terms of time for anal exhaust and defecation after surgery , the postoperative hospital stay, the gastrointestinal adverse reactions and complications after surgery. Results The nutrition and immunity indicators on day 7 after operation were significantly poorer and lower than on day 3 before operation in the parenteral nutrition group (P<0.05); the declines of TP and ALB were significantly contained in the enteral nutrition group (P<0.05). The time for anal exhaust and defecation in the enteral nutrition group was advanced 15.1 h and 27.9 h on average, compared to the parenteral nutrition group and control group, respectively. The rate of adverse reaction was significantly lowered (17.3%vs. 40.4%, P<0.05). The rate of complications in the enteral nutrition group was significantly lower than the parenteral nutrition group (P>0.05). Conclusion Enteral nutritional support under fast track process model for the liver cancer patients undergoing precise resection could improve clinical outcome.
